Scientists monitoring electrical activity of thousands of individual brain cells, In a study of patients with epilepsy, the researchers looked at the electrical activity of thousands of individual brain cells called neurons when patients performed memory tests.
They found that the pattern of cell firing occurred when patients studied a pair of words playing for a split second before they managed to remember the pair.
Memory plays an important role in our lives. Just as music notes are recorded as recording channels, it seems that our brains store memories in a firing pattern of neurons that can be reproduced repeatedly, the researchers said.
A team of researchers noted the electrical current from epilepsy patients who are drug-resistant while living with surgical implant electrodes to monitor brain activity, hoping to identify the source of the patient’s seizures.
This time also allows nerve activity to be checked during memory.
In this study, his team examined the activity of storing memories from our previous experiences, which scientists call episodic memories.
In 1957, the case of a patient with H.M. provides a breakthrough in memory research. H.M. unable to recall new experiences after surgery released part of his brain to stop the spasms. Scientists monitoring electrical activity of thousands of individual brain cells.
Since then, research has shown that episodic memories are stored or coded as a model of the activity of neurons that are reproduced by our brain when triggered by things like familiar odors or groups of earwigs. But how exactly that was done is unknown.
The researchers say: If we look closely at the data collected from patients, we think we can find an association between memory and neuronal fire patterns in humans that are similar to those in mice.
For this purpose, they analyzed the firing pattern of individual neurons in the anterior temporal lobe, the brain’s speech center. The stream is recorded when the patient sits in front of the screen and is asked to learn pairs of words such as cakes and foxes.
Researchers have found that the unique firing pattern of individual neurons is related to learning each new word model. If later the patient sees one of the words, e.g. For example, cakes, very similar shot patterns are only reproduced milliseconds before the patient correctly remembers the twin words Fuchs. Scientists monitoring electrical activity of thousands of individual brain cells.
These results indicate that our brain uses a different sequence of neural peak activities to store memories and then reproduce them when we recall past experiences.
They also showed that waves recorded in another area called the medial temporal lobe precede the repetition of the firing pattern observed in the anterior temporal lobe during learning.
According to the researchers, our results support the assumption that memories involve coordinated representations of neural flame patterns throughout the brain.
